<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight waited beneath the fluttering banners. His polished armor caught the last of the sunlight. “Frederick, I presume?” he called, stepping forward to take Thunder’s reins. “I’m Sir Roland. You’ve had a long ride—and the castle has a way of making first arrivals feel longer still.” Frederick swung down from the saddle, trying not to show how stiff his legs were. Sir Roland gave him an approving nod. “Come along, squire. The horses need tending, and I’ll tell you what your training will demand.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder slowed as Frederick reached the stable yard. A knight in a weather-worn green cloak emerged from between the stalls, carrying a lantern. “You must be Frederick,” he said. “Sir Roland. I was beginning to think the road had swallowed you.” “Not quite, sir,” Frederick replied, climbing down. Roland smiled and offered a hand to steady him. “Good. We’ll need you in one piece. Bring your horse inside, and mind the bay mare in the third stall—she dislikes strangers almost as much as I do.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> The stable doors stood open, spilling the warm scents of hay and leather into the evening air. A knight waited there, his blue surcoat marked with the silver emblem of a dragon. “Frederick!” he called. “I’m Sir Roland, the local knight. Welcome to the castle.” As Frederick dismounted, Roland glanced at Thunder’s foam-flecked flanks and softened his stern expression. “You’ve ridden hard. Let’s see your horse settled before we discuss your place here.” From somewhere within the stables came a sudden clatter, followed by a startled whinny. Roland’s hand went to the hilt of his sword. “Stay close, lad.” </nc-section>
